As organizations face more uncertainty than ever before, it has become imperative to engineer systems that are both resilient and responsive to changing conditions faster and in ways that make them stronger or more adapted.

This year’s conference looks at resilience as a property of software and focuses on engineering practices that build systems that are more secure, less brittle, and easier to change. We’ll focus on defining, measuring, and optimizing resilient systems and examine their response to stressors, whether those conditions are errors, threats, or market volatility.

Code Freeze 2023 encompass cybersecurity, devsecops, chaos engineering, observability, and sociotechnical principles all in the context of engineering systems that can thrive in uncertainty.
